Communication and Networking Riser Interface Connector(CNR)
The maiboard provides this Communication and Networking Riser(CNR) interface which can
support audio and/or modem functions . Furthermore, it provides a LAN interface for network-
ing functions. What its superiority compared with AMR is being able to support plug-and-play
function. Mechanically the CNR shares a PCI slot, thus when you insert the CNR card, the
neighboring PCI slot cannot be used.
CNR Interface Connector
By using an audio codec, the AC’97 digital link providing by CNR allows for cost-effective,
high-quality, integrated audio on the platform. In addition, an AC’97 soft modem can be
implemented with the use of a modem codec. AC’97 digital link allows several external
codecs to be connected to the ICH2. The digital link is expanded to support two audio
codecs for up to 6 channels of PCM audio output (full AC-3 decode) or a combination of an
audio and modem codec.
Chassis Security Switch (CHSSEC)
The connector connects to the chassis security switch on the case. The system can
detect the chassis intrusion through the status of this connector. If the connector has
been closed once, the system will record the status and indicate the chassis has been
opened. You can receive this information from QDI ManageEasy software.
